SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 421,768, dated February18, 1890. Application filed May 16, 1889. Serial No. 311,025. (No model)To aZ Z whom it may concern.-

Be 1t known that I, THEODORE SOHEFFLER, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented a certain new and useful Improvement in Snow-Flows, ofwhich the following is a specification.

My invention relates to that class of snowplows in which a series ofshovels rotate in in a casing having an aperture through which theshovels eject the snow, and has for its object the regulation of theaperture through which the snow is ejected, so that the snow may bethrown out either at the side of the casing or at the top thereof, or atany point intermediate the side and top, and, further, to provide adeflector to direct the deposit of the snow in convenient lines alongthe track.

My invention consists in forming in the casing for the snow-shovels anaperture extending, preferably, from below the horizontal center line toa point beyond the perpendicular center line thereof and providing aregulator for such aperture, such regulator preferably being providedwith an aperture of less area than the area of the aperture of thecasing and being adapted to slide on the easing and close the aperturethereof, except where it is coincident with the aperture in theregulator, whereby the line of discharge of the snow is varied.

My invention further consists in providing adeflector for theregulator-plate provided with an aperture above referred to, whereby theplace of deposit of the snow may be governed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a central vertical transverse section of the casing of myimproved snow-plow. Fig. 2 is a partial section and partial elevationthereof, the section being a vertical central longitudinal section ofthe lower half of the casing, and the elevation being taken with theobserver at the right of Fig. 1 and being of the upper half thereof.Fig. 3 is a section taken on the plane of the line 3 3 of Fig. 1.

In the drawings, a is the driving-shaft, upon which is mounted a hub 12,from which radiate spokes c. Carried by these spokes is a ring cl, whichserves to carry and support the shovels e, which are secured atthenouter ends to a ring or band f.

g is a hood, which is shown as trapezoidal in form, having its bottomsurface so shaped that the hood will descend below the heads of therails. This hood is also formed so as to present advanced cuttingportions to the snow-bank.

The parts above described may be of any desired construction; but Iprefer to have them of the construction shown in my application forLetters Patent filed April 16, 1889, Serial No. 307,490. 1

h is a casing, circular in cross-section, having an aperture, preferablyoblong in shape when developed, extending, preferably, between thepointsM-that is, from a point below the horizontal center line of thecasing to a point beyond the perpendicular center line thereof.

j is the regulator, which is shown in the present example of myinvention as a plate having an aperture smaller in area than theaperture of the casing. plate so that it will act as a regulator, it iscurved to conform to the outer surface of the casing, so as to slidethereon, it being mounted at each side on the casing, as shown insection in Fig. 3, With the inner side resting upon the back plate is ofthe casing and the front side resting upon the circular rim Z thereof,left after the aperture is formed, the broken lines in said figurerepresenting the top plate of the casing before the aperture has beenformed therein. To move the plate which forms the regulator in thisexample of myinvention, on one side thereof a rack-bar m' is mounted,and on angle-irons n 0 on the casing are mounted bearings for a shaft p,one end of which is provided with a crank-handle q, a pinion a" on theshaft engaging with the rack m on the cap-piece. By this arrangement ofrack and pinion an operator by the handle q may readily change theposition of the aperture of the plate with relation to the aperture ofthe casing, thereby regulating the position of the discharge-opening.

Carried by the regulator is a deflector s, which is shown as acontinuation of one side To operate this 1 of the aperture of theregulator, side plates 5' and end plate .9 being added, and the wholeforming a funnel for the regulatoraperture. This deflector serves todirect the deposit of the snow, and beingmovable With the regulator theline of deposit of the snow may be altered as convenience requires. Thebroken lines in Fig. 1 show the regulator-plate and deflector inposition to discharge the snow from the top of the casing.

t t are aseries of holes formed in the casing, with one of which a holeon the regulator may be brought coincident. A pin to being passedthrough the coincident holes will serve to secure the regulator inposition on the cappiece.

lVhat I claim is 1. In a snow-plow, the combination, with a casingprovided with an aperture, of one or more snow-shovels acting in saidcasing, and a rcgulatonplatc for the aperture of said casing, providedwith an aperture smaller than the aperture of the casing, substantiallyas set forth.

2. In a snoW-ploW,-the combination, with a casing provided with anaperture, of one or more snow-shovels acting in said casing, aregulatonplate for the aperture of said casing, provided With anaperture smaller than 4. 111 a snow-plow, the combination, with a casingprovided with an aperture, of one or more snow-shovels acting in saidcasing, a regulator-plate for the aperture of said casing, provided Withan aperture smaller than the aperture of the casing, and means formoving said regulator upon said casing, sub stantially as set forth.

5. In a snow-plow, the combination, with a casing provided With anaperture, of one or more snow-shovels acting in said casing, aregulator-plate for the aperture of said casing, provided with anaperture smaller than the aperture of the casing, means for moving saidregulator upon said casing, and means for holding it in a fixed positionWith relation thereto, substantially as set forth.

6. In a snow-plow, the combination, With a casing provided with anaperture, of one or more snow-shovels acting in said casing, aregulator-plate provided with an aperture smaller than the aperture ofthe casing, and a deflector carried by said regulator, substantially asset forth.

7. In a snow-plow, the combination, with a casing provided With anaperture, of one or more snow-shovels acting in said casing, aregulator-plate provided with an aperture smaller than the aperture ofthe casing, and a spout carried by said regulator, substantially assetforth.

This specification signed and witnessed this 11th day of May, 1889.
